Aluminum-polymer capacitors, or simply "polymer capacitors," are a type of electrolytic capacitor that uses a gel-like electrolyte. Unlike traditional electrolytic capacitors, their liquid electrolyte is immobilized, so they can operate at wider temperatures, higher voltages, and higher temperatures than typical aluminum electrolytic capacitors. The RHT1A391MDN1KX is a type of polymer capacitor that is ideal for high-temperature and high-voltage applications.

The RHT1A391MDN1KX is specifically designed for surface mounting on printed circuit boards (PCBs). It is a high-quality, miniature and low-ESR aluminum-polymer capacitor. It is designed for DC bias filtering and interference suppression in applications such as computer motherboards, servers and switchboards.

The RHT1A391MDN1KX is engineered to handle high frequency and larger current load compared to standard capacitors. It has a maximum operating temperature of +105 °C with a maximum ripple current of 6.0 A rms @ 25 °C. The device has a low ESR of 0.13 Ohm @ 100 kHz and 0.60 Ohm @ 10 MHz.

The RHT1A391MDN1KX is a polarized capacitor, meaning that the polarities must be observed during installation. This ensures that the capacitance is maximized and that it has proper alignment with the circuit. The capacitor consists of a metalized anode, a metalized cathode, and sealed anode-cathode insulation that keeps the anode and cathode from contacting.

The RHT1A391MDN1KX has an electrical construction which puts two identical silver-plated aluminum foil electrodes together with a dielectric consisting of plasticized epoxy resin. When voltage is applied, a dielectric strength develops between the anode and the cathode, allowing electric current to flow between them. This creates a charge in the capacitor\'s electrodes, stored potential energy. The RHT1A391MDN1KX has a stablization film which helps to maintain a constant capacitance even when voltage or temperature changes.

The RHT1A391MDN1KX is ideal for applications where high reliability and extraordinary thermal stability are needed. Its specialty film combined with its high-temperature performance provide long capacitor life and improved temperature coefficients. Its low ESR also allow it to have excellent charge-discharge characteristics, potentially improving circuit efficiency while saving power consumption.

The RHT1A391MDN1KX is a versatile aluminum-polymer capacitor designed for a wide range of applications. It is suitable for filtering, decoupling, power supply and timing applications, offering excellent thermal stability, low ESR, and high reliability. Its high voltage rating allows it to be used in high-power applications. It is also extremely easy to mount on a printed circuit board and its low ESR ensures it is able to handle ripple current without overheating.
